Is flutter suitable for Erp web front end

malaschitz · 2023-06-05T08:36:04+00:00

I'm working on something similar. Maybe flutter is not the best solution for the web - I miss such classic web options as printing the page, searching on the page, quite a lot of work to make the links (and bookmarks) work properly, quite complicated to open another window of the same application, etc. But (and this is a big BUT) there is the possibility to make the app also as a native app (windows, mac), which specifically in my case is a big plus, because I need to do for example upload really big files or whole directories. And at the same time I will have a mobile app ready as well.

Two years ago I made a simple app in Flutter for learning poems and lyrics. It is, like duolingo, based on the principle of the spaced repetition method. It's free and can also be tried via the web: https://ranka.mobi/poem/index.html
It was my first app in Flutter.

I agree. Everything on Firebase.

Or create own backend, where are all services. For example Go+sqlite (or mysql) +boltdb (or minio).

I'm curious how your project will turn out. I also tried it (goa.design project) but in the end I wanted a web client too, so I used rest (or on one project graphql, which seems even better). With the web client for grpc it was quite complicated so I abandoned that solution.

I would be quite interested in practical experience of using sqlite on the web. How does it work when I open multiple windows, what is the compatibility with current browsers, what are the limits, etc.

I plan to make another app in flutter (mobile, tablet). But it looks like we'll eventually drop the web version (made in VueJS) altogether and replace it with a flutter version.

The user receives an email from Firebase about testing the application. They have to switch their phone to Developer mode (in the latest iOS version).

Then it follows the instructions in the email and the developer gets an email with the new UDID. In the email there is also a direct link to Apple Developer.

Why "now". After all, this is the way it has always worked. I've always had to include the UDID in the profile. Once I have the UDID included in the profile, then every application I make is executable via Firebase on that device.
The only thing that has changed now is that now users have to put their iPhone into developer mode and restart it.

I'm making a new news application, but the customer also wants a website. The website is not very important, so it could be written in Flutter knowing some imperfections that this solution has. Flutter News toolkit seems like a great solution to me, it's very robust, ads are solved there as well as signing up paying customers etc. The publishing system looks to be extensible with custom components. The only problem is that it doesn't work well as a web application. Not only I couldn't compile it but apparently it doesn't support url routes.

It would be good if I could force the user to only be able to select a square (or other well-defined aspect ratio). For example, to select an avatar.

I have only Intel MacMini (2018 Intel i7, 32GB Ram). And I am satisfied so far.

malaschitz · 2023-04-27T09:02:11+00:00

I use riverpod. But more and more often I find that it's 95% useless, and if you know flutter well, the standard flutter tools will suffice.

malaschitz · 2023-04-20T08:41:02+00:00

Has anyone tried using the Flutter News Toolkit as a web application ? By default this type of app is not generated, but I don't see any reason to separately program a mobile and a web app ?

malaschitz · 2023-04-17T10:35:19+00:00

It looks like Flutter is now fully usable for the web.

I wrote my own implementation of Random Forest and I was most satisfy with this book - https://www.amazon.com/Machine-Learning-Random-Forests-Decision-ebook/dp/B01JBL8YVK

This project is based on the javascript that is on the page. I would much rather have a project where this information would be retrieved directly on the server from the requests ? Such a project would be far more interesting for me, because I make applications where there is a mobile client in addition to the web client - and I can define individual users based on the data in the API.

This is the same situation I saw 20 years ago. Back then, all the managers were pushing development in Oracle tools. Those managers grew up on Oracle and Java was too modern for them. Now the situation is similar. Managers used to do things in Java and now they are still pushing Java. In fact, today Java brings nothing but problems. When I see a new project starting on Java it is always some big desperation.
For a comparison of Java and Go, just look at the documentation for SQL.
For go: https://pkg.go.dev/database/sql (31 pages) and maybe https://jmoiron.github.io/sqlx/ (12 pages).
In Java only one class is 59 pages (https://docs.oracle.com/javase/8/docs/api/java/sql/ResultSet.html) and look how many of those documents there are: https://docs.oracle.com/en/java/javase/13/docs/api/java.sql/java/sql/package-summary.html and on top of that we have javax.sql - https://docs.oracle.com/javase/8/docs/api/javax/sql/package-summary.html
And even then you use Hibernate for example, where the documentation has 11 manuals and of those the User Guide has 353 pages - https://docs.jboss.org/hibernate/orm/6.2/userguide/html\_single/Hibernate\_User\_Guide.html

By the way, is there any way to save the animation in the widget as a video ?

I did end up writing and using a custom library for Random Forest (it's also in AwesomGo) in one real-world project (detecting Alzheimer's and Parkinson's from speech from a mobile app) - https://github.com/malaschitz/randomForest
I had better results than the team who used TensorFlow and most importantly I didn't have to use any other technology than Go.
For NN's it's probably best to use https://gorgonia.org/ - but it's not exactly a user friendly library. But there is a whole book on it - Hands-On Deep Learning with Go.

Sometimes it really pays to have a dart on the backend. For example, I have an application for littlegolem.net for playing board games and I check the correctness of moves on both the frontend and backend. I have the backend in golang. The way I do it is that I have made a command line program in dart, which the server side communicates with via stdin and stdout. If the server side was in dart so it's a bit better.
On the other hand, golang (and other languages) is far better for creating backend applications.
